Coleman Insulated Bottle 1.75 qt
Lower concern. Stainless steel insulated bottle with no known PFAS coatings.
Coleman insulated bottles use stainless steel construction without reported nonstick or water-resistant coatings that typically contain PFAS. No brand disclosure or third-party testing available, but material profile suggests lower risk.

The full breakdown
What it's made of and why it matters
This bottle uses a stainless steel outer shell (typically 18/8 or 304-grade), which is chemically inert and does not leach metals into beverages under normal use. The insulation layer is closed-cell foam, likely polyurethane or polyethylene, sandwiched between the steel exterior and an inner plastic or steel liner. Foam insulation itself poses minimal leaching risk because it does not contact the liquid directly unless the inner barrier fails.
The brand's record and disclosure
Coleman is a major outdoor equipment manufacturer owned by Newell Brands. The company does not publish detailed material safety data sheets or third-party certifications for this specific bottle model. No major product recalls or chemical contamination incidents are on record for Coleman insulated bottles. The brand's silence on PFAS use in coatings or sealing compounds is consistent with industry norm for this product category, though transparency remains limited.
How it compares in its category
Stainless steel insulated bottles are among the safest options for beverage storage; they avoid concerns present in some plastic-only or coated-aluminum alternatives. This 1.75 qt capacity sits in the mid-range for personal or small-group use. Comparable brands (Hydro Flask, YETI, Contigo) typically use similar stainless steel construction and do not disclose PFAS in non-coating materials. Coleman's price point is generally lower than premium competitors, which may reflect simpler interior finishes rather than material differences.
If you buy it
Hand wash rather than dishwashing to minimize wear on any sealant or gasket materials. Do not fill with boiling water immediately; allow hot beverages to cool slightly to avoid stress on insulation seams. Inspect the gasket (lid seal) annually for cracks or hardening; replacements are typically available. If the interior develops visible rust, corrosion, or leaks after years of use, retire the bottle rather than continuing to use a compromised liner.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Inner liner corrosion or degradation
If the inner stainless steel or plastic liner is scratched or punctured, moisture can enter the foam insulation layer and promote rust or mold growth over years. This is a durability issue rather than acute toxicity, but compromised liners should be replaced.
Gasket/seal material off-gassing or leaching
Coleman does not disclose the composition of lid gaskets or seals. These are typically silicone or rubber but are not known to leach harmful compounds at room or cold temperatures. Heating beverages above 65C may accelerate minor leaching, though no reported incidents exist for this product line.
Foam insulation particle shedding
Closed-cell foam does not shed particles into liquid under normal use because it is fully encased. Damage to the outer or inner shell could theoretically expose foam, but this would be visible and obvious; no systemic complaints are on record.
Heavy metals in stainless steel
Grade 304/18-8 stainless steel contains iron, chromium, nickel, and molybdenum. These remain bound in the alloy matrix and do not leach into room-temperature or cold beverages. Acidic hot drinks (lemon water, vinegar) may accelerate minute surface leaching over prolonged contact, but amounts are negligible.
Adhesive or adhesion promoter residue
Coleman does not publicly specify adhesive or coating methods used to bond the foam layer. If epoxy or urethane adhesives are used without full cure or outgassing time before shipment, trace volatile compounds might off-gas initially. Airing the bottle for 24 hours before first use mitigates this minimal risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
